INTRODUCTION 

Whether your communications site is off the grid, or designed to operate from DC power for 
uninterrupted quality of service, certain components still require high quality, reliable AC sine 
wave power to operate. 

The ICT SITE INVERTER 300 is a low profile, high performance sine-wave inverter that 
converts DC energy from your battery source into 300 watts of utility grade power for site 
equipment that requires AC electricity, such as radio links, multiplexers, routers, or digital 
video recorders.  ICT inverters provide extremely low harmonic distortion and high efficiency, 
meaning that your equipment receives extremely quiet, high quality power.  

Up to three ICT SITE INVERTER 300’s can be mounted in a single 1RU 19 inch rack shelf, to 
provide almost 1kW of power (non-parallel) and six AC outlets in an ultra-compact, space 
saving design.   

Other options include an accessory kit that provides two AC outlets on the front faceplate of 
the inverter rack. 

FEATURES

The ICT SITE INVERTER 300 is designed specifically for communications site applications, 
and includes the following features:

- Two rear-facing AC outlets for easy access to the equipment that needs to be powered.

- Rear-mounted DC input studs for connection to the DC battery source.

- A grounding stud on the rear of the unit.

- Front mounted power switch and LED indicator lights.

- Thermo-controlled, ball bearing brushless cooling fan blowing front to back ensures the best 
thermal performance and longevity for the internal components.

- Air intake is from the front of the unit.

- LED indicators provide information on AC status and on the built-in protection features, 
including input voltage condition, overload, and temperature shutdown conditions.

- Operating temperature range from –20C to +60C.

- Capable of handling up to twice its rated capacity, or 600 watts, for up to three seconds.

OPTIONS

- 1RU 19” mounting rack (model number ICT-RM1U) holds 1, 2, or 3 inverters.

- Front AC Outlet Kit (ICT-ACF) provides two AC power outlets on the front of the ICT-RM1U 
rack mount kit (requires one open mounting position and one Site Inverter 300). Includes AC 
power  cord to route AC from the Site Inverter 300 to the front facing outlets.
